The Role of TOR1A Polymorphisms in Dystonia: A Systematic Review and Meta-Analysis.

Importance: A number of genetic loci were found to be associated with dystonia. Quite a few studies have been contacted to examine possible contribution of TOR1A variants to the risk of dystonia, but their results remain conflicting. The aim of the present study was to systematically evaluate the effect of TOR1A gene SNPs on dystonia and its phenotypic subtypes regarding the body distribution.

Osteoid Osteoma of the Femoral Neck: Use of the Half-Moon Sign in MRI Diagnosis.

Objective: Osteoid osteoma is a benign bone tumor that is commonly located in the proximal femur. Although CT is helpful in the diagnosis of osteoid osteoma, patients in whom the clinical presentation of the tumor is atypical are first referred to undergo MRI, which yields a high percentage of false-negative or inconclusive results. We sought to explore the association between a half-moon sign of bone marrow edema and the presence of osteoid osteoma of the femoral neck.

The role of oral vitamin K antagonists in the outcome of infrainguinal bypass procedures.

We investigated the role of oral vitamin K antagonists (VKAs) in graft patency, limb salvage, major and minor bleeding rates in patients undergoing infrainguinal bypass surgery. Five randomized-controlled trials (RCTs; n = 3746 patients) comparing VKA versus non-VKA treatment outcomes in patients undergoing infrainguinal bypass surgery were analyzed. The VKA treatment was associated with improved graft patency rates when a vein graft was used (risk ratio [RR]: 0.

Objective: To investigate the effect of metformin administration on the expression of endometrial corticotrophin-releasing hormone (CRH) and urocortin (UCN) in the midluteal phase of the cycle.

Design: Experimental study, performed in 2010-2011.

Setting: University hospital.

Soluble FMS-like tyrosine kinase-1 (sFlt-1) and serum placental growth factor (PlGF) as biomarkers for ectopic pregnancy and missed abortion.

Context: Diagnosis of early pregnancy failure is hampered by the lack of reliable serological markers.

Objective: We assessed whether a single serum measurement of placental growth factor (PlGF) and the soluble Flt-1 (sFlt-1) receptor of vascular endothelial growth factor at 6-8 wk gestation could differentiate failed pregnancies, whether ectopic pregnancies (EP) or missed abortions (MA), from healthy intrauterine pregnancies (IUP).

Design And Setting: We conducted a prospective clinical study at a tertiary university hospital between January 2009 and February 2011.

The role of gonadotropins in the follicular phase.

Folliculogenesis in humans is a lengthy process that involves several regulators. Pituitary gonadotropins play crucial roles in the late stages, particularly in the last 15 days of follicle maturation. During the intercycle rise of follicle-stimulating hormone (FSH), selection of the dominant follicle takes place.

Immunophenotypic evaluation of DNA mismatch repair markers in 2 cases of synchronous histomorphologically distinct gastric adenocarcinomas with gastrointestinal stromal tumors of the proximal small bowel.

Objectives: To assess the prognostic value of combined mismatch DNA repair (MMR) phenotyping in 2 synchronous histomorphologically distinct gastric adenocarcinomas (GADCs), each accompanied by gastrointestinal stromal tumors (GISTs) of the proximal small bowel.

Summary Background Data: A 72-year-old female and a 55-year-old male patient were submitted to partial and total gastrectomy, respectively, with synchronous resection of a GIST in the proximal small bowel. The 2 patients attained contrasting survival outcomes.

Sequence-based genotyping HPV L1 DNA and RNA transcripts in clinical specimens.

We developed a direct sequence-based genotyping method to detect single and multiple HPV L1 DNA and RNA types in genital and dermatological specimens. Our method couples PCR amplification of a highly conserved HPV L1 segment using a broad spectrum-generic primer cocktail mix with automated sequencing of amplified PCR products, followed by GenBank sorting of sequencing data. We genotyped 5 skin and 30 cervical HPV DNA-positive specimens using this method and established its first experimentally derived working cutoff value with the aid of commercial hybridization-based techniques.

Use of albumin polymers during breast cancer surgery improves postoperative seroma outcome.

The effect of an albumin polymer instillation (Bioglue® Cryolife, Inc., Kenneaw, GA, USA) during breast cancer surgery on postoperative seroma formation was evaluated. Two groups of 34 consecutive patients, treated during operation with and without polymer, were followed postoperatively by weekly ultrasound and clinical evaluation.

Phenotypic mismatch repair hMSH2 and hMLH1 gene expression profiles in primary non-small cell lung carcinomas.

Background: Defects in the human DNA mismatch repair genes (MMR) hMSH2 and hMLH1 are responsible for the development of sporadic and hereditary colorectal cancers. The role of MMR genes in the pathogenesis of lung cancer has not been elucidated. The aim of this study was to address the phenotypic mRNA expression profiles of mismatch DNA repair system in lung cancer.

The fat content of small primary breast cancer interferes with radiofrequency-induced thermal ablation.

Background: Radiofrequency (RF) thermal ablation is a minimally invasive technique of local mass elimination with variable efficiency.

Methods: Ten patients with small primary breast cancer diagnosed preoperatively by core needle biopsy were ablated percutaneously by an RF (Radionics Cool-tip) device operating on impedance control mode. The percent fat-containing area was calculated in each slide of a total of 47 slides introduced to IQ materials software image analysis.

Comparing normal primary endocervical adenoepithelial cells to uninfected and influenza B virus infected human cervical adenocarcinoma HeLa cells.

Human adenocarcinoma HeLa cells surviving infection with low (10(-9) units), medium (10(-6) units), and high (10(-2) units) influenza B titers were compared to their uninfected precursors and to normal endocervical adenoepithelial and metaplastic cells using Papanikolaou-staining method and immunocytochemistry. Normal primary endocervical and infected HeLa cells surviving infection shared similar morphologic, phenotypic, and divisional patterns that differed drastically from those of uninfected HeLa cells. The number of infected hosts surviving 6-7 days of viral exposure did not change during 3-week follow-up period, and their cyclin E levels suggested that they had been arrested to the G1 phase of the cell cycle by viral stress.

Quantitative determination of human telomerase reverse transcriptase messenger RNA expression in premalignant cervical lesions and correlation with human papillomavirus load.

Expression of human telomerase reverse transcriptase (hTERT) messenger RNA (mRNA) and human papillomavirus (HPV)-16 load were quantified using real-time polymerase chain reaction and correlated with cytological findings and the presence of HPV infection in cervical specimens. Human telomerase reverse transcriptase mRNA expression was evaluated in 15 (20.5%) of 73 specimens of atypical squamous epithelial cells of undetermined significance, in 62 (39.

Post-operative delirium after hip fracture treatment - a review of the current literature.

Delirium is a common accompaniment of physical illness in old age, affecting approximately one out of five of those admitted to medical wards, the number being higher for elderly with fractured femurs. Although its existence has long been recognized its exact pathophysiology has not yet been fully elucidated. The present article presents up-to-date information concerning the etiology, pathophysiology, prevention and treatment of the post-operative delirium after hip-fracture treatment.

Hippocrates: a pioneer in the treatment of head injuries.

Hippocrates' treatise On Wounds in the Head represents an excellent source of information regarding the extent of experience with head injuries in classical antiquity. On the basis of clinical observation, the great physician gives an accurate description of the external appearance and consistency of the cranium. Fractures of the cranium are divided into six main categories, each of which is discussed separately, regarding its mechanism, clinical assessment, and treatment.

Results And Conclusions: Twenty-two studies enrolling a total of 3096 patients were identified from 1984 to date.

Hierarchical arrangement of psychiatric symptoms in the context of schizophrenia.

Foulds' model proposing a four-class hierarchical structure of mental illness represents an interesting dimension of psychiatric research and discussion and probably has a significant potential on diagnosis, taxonomy, therapeutics and theory. Psychiatric symptoms were investigated in a group of 244 schizophrenic patients with the purpose of analyzing Foulds and Bedford's notion that psychiatric symptoms are arranged hierarchically. To achieve this the R (recent) version of the Delusions, Symptoms, States, Inventory (DSSI) was administered in the form of a constructed interview to these patients.
